口腔全科住院医师规范化培训模式下牙周龈下刮治效果的教学研究

Study on the effects of periodontal subgingival scaling under the mode of standardized residency training of stomatology general medicine

目的观察口腔全科住院医师规范化培训不同阶段住培医师牙周龈下刮治的效果。方法用分层随机法选取30名浙江大学医学院附属口腔医院牙周科轮转的住培医师,按照入科1个月、3个月和6个月分组。比较各组牙周龈下刮治后临床牙石残留率的差异。采用SPSS 23.0软件进行Kruskal-WallisH检验。结果3个月组和6个月组的临床牙石残留率低于1个月组。3个月组仅对浅袋和前牙区能够达到有效刮治。与1个月组相比,6个月组能够降低探诊深度为4~6 mm刮治位点的临床牙石残留率,但对于后牙区刮治仍存在不足。结论经过3至6个月的住培培训可以提高牙周龈下刮治的效果。针对不同阶段的住培医师应该制订合理的考核评估体系,并且在龈下刮治培训中加强对后牙和牙齿远中面的训练,以期更有效地提高口腔住院医师规范化培训的质量。

Objective:To observe the effects of the periodontal subgingival scaling in different stages of standardized residency training of stomatology general medicine.Methods:Thirty residents in Affiliated Stomatology Hospital of Zhejiang University School of Medicine were recruited by stratified randomization and divided into three groups,including 1-month group,3-month group and 6-month group.The residual ratio of clinical calculus was compared after periodontal subgingival scaling among groups.SPSS 23.0 was conducted for Kruskal-Wallis H test.Results:The mean residual ratio of clinical calculus in 3-month group and 6-month group were significantly lower than that in the 1-month group.In the 3-month group,the scaling could only achieve the effective results at the shallow pockets and anterior tooth area.Compared with the 1-month group,the 6-month group significantly decreased the residual ratio of clinical calculus for the sites with pocket depth of 4-6 mm,but there were still insufficiency to deal with the posterior tooth area.Conclusion:The 3-6 months residency training of periodontology could improve the effectiveness of the periodontal subgingival scaling.We should establish reasonable assessment and evaluation system according to different stages of residents,and the subgingival scaling training in the posterior areas and the distal interproximal sites should be reinforced in order to more effectively improve the quality of the standardized residency training.
